A review of a Club Etcetera show begins by describing it as "one of the few local
engagements [Davis] has not canceled," and goes on to capture nicely the Septet's
performance: "His group is improvising, listening to each other, throwing phrases
back and forth. They are not working under predefined changes or chord progressions.
Neither are they being guided through the performance of a piece they have rehearsed
to perfection with the score in front of them. Davis is giving direction to their
improvisation, establishing a control that lessens the low points in communication
that high-energy improvisational music is prone to suffer from."

Another review, this one from Detroit's Masonic Auditorium, was less enthusiastic:

On Sunday, February 10, the legendary Miles Davis turned out one of the worst
performances of his career at the Masonic Temple in Detroit. It started out badly,
as Miles was an hour and a half late... When Miles finally showed up, things went
for the worse. His band was sensational, no, indescribably delicious, but Miles
appeared sick and possibly drunk and played out of key, and without energy. He
kept spitting on the floor, grossing the audience out. Amid catcalls and boos
(his pants were even falling down), Miles finally walked off stage, only to
return after heated arguments offstage and continue with a lackluster showing.
It's sad, too, as the other people in his entourage were remarkable in their
show, and also seemed irritated with Miles's unusual weirdness...
